To all whom it may concern:

lie it known that l, (lmwronn Zmonnn, :i ritizen of the linited States.residing et liurlierton. in the county of Summit und Stute of Ohio,huive invented new and ilseful Improvements in Tire Wrappingr undlinwropping Apparatus, of whieh the following is u specification.

ln u contemporary upplii'ution filed Muy 26. i919, Serial No. 299,606 lshow und de scribe un organized mechanism lor wmp ping und nnwruppiugtires.

Une ohjert ot my 'n'esent sole. invention is to improve the apparatusalluded to by the provision of means whereby' the. teni-inni to nhiehthe wrapping tope is suhjwted muy he nieely regulated.

`an les of Fig. 1.

.e nother ohjeet is to improve the .said up pnratus by the provision ofmeans adapted to be adjusted to tires of different sizes in crosssection und also adopted to serve ns a means whereby the speed ot' thctire movement: may he vreadily regulated` on the theory that when thetire is moved slowly about its center it will he closely wrapped Whilewhen the 'tire is move-d comparatively fast it Will he widely wrapped.

To the attainment. of the foregoing the. invention consists in theimlirovement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made aV part hereof:

Figure l is an elevation of the apparatus as improved.

Fig. 2 is a broken elevation taken at right ig. 3 is a detail view inplan of the cradle of the apparatus.

Fig. 4 is a detail transverse section taken at right angles to Fig. 3.

Fig. 5 is e diametrlcal section illustrative of the tension regulatingmeans.

Figs. 6 and 7 are. detail sections taken in the planes indicated bv thelines 6-G und 7--7,-respectively of Fig. 5.

Similar numeruls of reference designate corresponding parts in all ofthe Views oi the drawings.

'The general construction of the improved apparatus is similar to theeneral constrnction of 'the apparatus disc osed in my von temporaryapplication supra, and need not therefore be described herein except ineonjunction with tinl novel tentures that von stitute the present inwfution.

11i furtherance of one part of my present invention l provide the `spool8l in its opposite sides with trains-Verse apertures 812 ietu'een the[graine member 26S and the Suid spool Hl l interpone :i disk TT; thespool 5%] und the disk TT living mounted on the liournul T5. und the.Quid journal being provided with u rollin* :it T3". Figi. 'The Suidjournul To is ('urrii-d h v u revoluhle"annulus Ell. The dish l? isprovided with the eXteriorly threudi'd lm-w T5". und is confined uguiustthe eollur in hy n diunietrirul pin T5, i-urried in (he journal T5.

Looseiy .'-lurroiuidiinr the sleeve of the disk TT is :i plete l,:1nd arranged ut the outer side oi the plete. l und threaded on the saidsleeve l i nut il. The plate lA is equipped with outnardliI extendingrpins 3 to enter the apertures Si of the spool` und between the pluto lund the disk T7 and surrounding the disk sleeve is u-houjed` springllore. it -will he apparent from the foregoing that anlyiustment of thenut 2 toward the dislr TT n ill lie uttendedffbif in! crease of thetension to which the tope on the spool 8l is subjected. while. movementon the said not 2 in u direi-l ion muy from the disk 'Ti' will bringshout the lessening of the said tension. lt'` will he noiired in thisconnection that rotor)r motion is trans-- mitted from the disk T? to thespool :81 through the medium of the bowed spring 4, the disk 1 and thepins 3.

By comparison of Figs, Stond 4 itmill @e noticed that the cradle ol theimprornd up pnrutus comprises hod'xT heirs 1R unds 18. und that suidbody hars are tule-ruined :it 14 between standards. Extendingtrousversely between the end portions of the said body hors are threadedholts or rods 15 on which theA hody bnr 13*1 is laterally ndjusted. Thiswill he hotter understood hy reference. to Fig. fl wherein it will henoted that u combined nut und sprocket geur 1i. is mounted on thethreaded portion of eueh rod l5 and that u tuhular extension l1 of theelement. il extends loosel)Y through the. hodybar i3 und is equipped at.the inner sido oi the hotly bnr with u collar l2. se mired to thetuhulnr extension by n'set Screw 12a. Loosely mounted on the innerportions of the rods 15 are sprocket gears 17, and Fixed with res ect tothe said sprocket gears 17 are beve ed roll members 16 on which arelateral pins 16. Also loosely mounted on the rods 15 are roll members16" in which are sockets 16'that receive the pins 16?. The elements 11are connected by a sprocket belt 21, and one of thesaid elements 11 isprovided at 22 with a 'crank handle for the convenient turning thereof.Consequentl when the crank handle 22 is turned the ro l members 16 willbe moved outwardly or inwardly on the rods 15 according to the directionof rotation. It will also be apparent that the roll members 16 and 1Gbwill ut all times rotate together as a unit, and that by regulating thedistance between the roll members 16 and their complements 16 the cradlemay be adapted to handle to advantage tires of different sizes in crosssection. Moreover it will be appreciated that inasmuch as in the oeration of the apparatus the tire, indicated by 11", is moved about itscenter through the medium of the roll members of the cradle, the speedat `which the tire is so moved may he increased by` movin r the rollmembers 16" toward the roll mem ers 16 and may be lessened by moving theroll members 16" away from the complementar members 16,

The genera Voperation of my apparatus as improved is similar to that ofthe apparatus of my said contenlporary application and therefore it isunnecessary to describe the same herein.

Having 'described my invention, what I claim and desire to secure byLetters-Patentis:

1. An organized mechanism for wrappn or unwrap ing a tire, comprising acra e having ro ls adjacent to its ends and adpted Ato l'ie'driven; eachof said rolls havixg inwardly beveled members and being` u justable asto Width and atlaptedto seat a tire.

2. An organized mechanism for wrapping or unwrapping a tire, comprisingwith respect to the other and the inner sides of which members aretapered.

3. An organized mechanism for wrapping or unwrappingl a tire, comprisinga cradle havin r rolls adjacent lab/its ends and adapted to lie driven;each of said rolls comprising members tapered at their inneil sides andone ot' which is adjustable with respect to the other, and means toadjustably fix the adjustable members with respect to the other members.

4. In an organized mechanism for wrapping or unwrapping tires, thecombination of a cradle. and spaced rolls carried by the cradle andadapted to support and feed a tire; each of the said rolls icingadjustable and shaped to seat tires of different cross sections and toregulate the specd of feed of the tires. .l

5. In a. tire Wrapping. or unwrapping mechanism the combination of aframe merobcr, a revoluble annulus, a journal carried by said annulus, adisk loose on the journal and revoluble by the frame member, a spoolloose on the journal, a nut threaded on the disk, a plate loose on thedisk at the oppo. site side of the nut to the spool and engaged with thespool, and a springl interposed betwecn the disk andsaid plate.

6. In a tire' Wrappinlg or unwrapping mechanismthe cradle comprisingrbody bars one of which is adjustable laterally toward and 4from theother, journals extending between said -body bars, inwardly beveled rollmembers loose on the journals, complementary inwardly beveled rollniei'nbers loose on the journals, and movable toward and from the firstnamedroll members und having sliding connection therewith, and meansconnecting the last named roll members and the adjustuble'body bar andthreaded on the journals and rotatable in concert.

In testimony whereof I aiiix my signature.
